In a move to ensure the most reliable and precise tracking of environmental progress, the Washington State Department of Commerce has submitted updated greenhouse gas emissions figures for inclusion in the latest state climate report. These revisions were prompted by a comprehensive review that identified discrepancies in previous data sets, underscoring the department’s ongoing commitment to transparency and scientific rigor. Stakeholders and policymakers now have access to a refined dataset that better reflects statewide emissions patterns across key sectors.

The corrected data highlights notable shifts in emissions contributions, offering new insights that will inform future climate strategies. Key updates include:

  • Transportation: Adjusted downward by 5%, reflecting improved vehicle efficiency and updated vehicle miles traveled estimates.
  • Industrial Processes: Slight increase of 3%, accounting for recalculated outputs from manufacturing facilities.
  • Residential Energy Use: Reassessed based on more recent consumption trends and weather normalization methods.
